LEATHER -STAKING MACHINE SPECIFICATION forming part of Letters PatentNo. 447,180, dated February 24, 1891. Application filed July 9, 1889;Renewed January 31, 1891. Serial No. 379,790. (No model.)

To all whom it may concern: Be it known that I, EDWARD HAYES, of Lynn,county of Essex, and Commonwealth of Massachusetts, have invented acertain Improvementin Leather-Staking Machines for Ourriers Use, ofwhich the following, taken in connection with the accompanying drawings,is a specification.

This invention relates to that class of ma- 1 chines used by curriersfor sleeking, softening, or staking leather, and the nature thereof ishereinafter fully described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation of themachine embodying my invention. Fig. 2 is an elevation of across-section on line 22 of Fig. 1. Fig. 3 is an elevation of alongitudinal vertical section of the machine shown in Fig. 1. Theworking parts of the machine are mounted upon a suitable framework,which is designated in thedrawings by the letter B. To that endlongitudinal ways a, Fig. 2, are secured to the frame-work and supportthe 2 5 members I) e. Said members are connected by a hinge or knucklejoint E, and that portion of the knuckle which fixes to the member e ismade with grooves to receive the said ways a a to the end that alongitudinal re- 0 ciprocating movement may be imparted to the saidmember e along said ways. The member 1) travels with the memberelongitudinally, but it also has a vertical reciprocating movement bytilting on the joint E, which 3 5 movement is imparted by mechanismdescribed hereinafter. I The longitudinal movement aforesaid is impartedto the members 6 b by means of a mechanism comprising the wheel A andpit 40 man H. To that end a suitable driving-power incident to pitman His compensated for by the tongues and wedges arranged (not shown) in themechanism in the usual 'manner.

Attached to the pitman H are brackets N, which support a pin 4:, Fig.'3, that operates in a longitudinal groove 5 of the lever 6. Said lever6 is connected with the member I) by a pin 7, on which the member isallowed to turn loosely. Said lever is further provided with a pin 8,which extends from its bottom end into a cam-groove 9, cut in the member6. This arrangement causes the member I) to be tilted on its joint Ewhenever the wheel A is made to turn round. The member I) is provided onits end with a Wheel 10, preferably composed of rubber, and a knife 12,composed of wood, in the usual manner. The member 6 supports knives 13and lat vhich are mounted on a hinged plate 15, to the end that theknives may be adjusted vertically relatively to the wheel 10. Saidvertical adjustment is obtained through thumb-screw 16, arranged asshown.

In operating this machine the workman holds the hide or leatheroutstretched in his hands, and as the members open sufficiently topermit it he moves the leather in between the knives and wheel 10 andholds it there, while the said members I) c are moved vertically andlongitudinally, as before described, to perform the staking operation.8o

7 The operation of the parts more particularly is as follows: Supposingthe disk to turn and carry the pin f-to its lowest point, the pitman Hwill be tilted and assume a downwardly-inclined position from the pin hto the pin f. During this movement the pin t works in the slot 5, andthe vertical movement of said pin is without effect on the member I);

but its lateral movement due to the tilting of the bracket N toward thedisk will cause the 9 pin to bear against the wall of the slot and tiltthe lever 6 on its pivot, causing the lower end to move forward and thepin 8 to ridein the lower part of the slot, which of course drawsdownwardly the lever G and operates the member I). In the rise of thepitman H the lever 6 is tilted to the position shown, the pin 8 bearingin the high part of the groove,

and causing the forward part of member I) to oted lever G, pivotailyconnected to the pitto move toward the member 6.

Having thus described my invention, I claim--- In combination, theframe, the member 6, the pivoted member I), the staking devices on saidmembers, the pitman H for reciprocating the said members, and means foroperating the memberb on its pivot, consisting of a pivman and to themember 12, substantially as described.

Signed at Lynn this 25th day of June, A. D. 1889.
